PAPER BAG.

To all whom t may concern:

Be it known that I, Fnnn R. SKINNER, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in laper Bags, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in paper bags, having folding flap constitutingr a closure for the open end thereof, and refers more particularly to means for locking the flap in the closed position and permitting it to be opened at willfand at the same time serving as a handle by which the bag may be conveniently carried.

rl`he main object is to make the combined lock and handle as an integral part with a minimum waste of stock, or in other words to provide the front side of the open end of the bag with a tongue adapted tov pass through the opening in the flap as the latter' is folded to its closed position, and to provide said tongue with opposed wings capable of folding within the area of the flap opening and of unfolding beyond the walls thereof, when the flap is closed for locking said flap against accidental opening. v

Another object is to provide the tonguel with an aperture through which the finger may be readily passed for carrying the bag. Other objects and uses relating to specific parts of the bag will be brought out in the following description.

In the drawings, Figures l and 2 are front elevations of a paper bag embodying the features of my invention, the flap being closed in Fig. 1 and open in Fig. 2.

Fig. 3 is a plan of a blank for forming the bag shown in Figs. l and 2.

Fig. 4 is an enlarged transverse sectional viewtaken on lines 4-4 Fig. l.

As illustrated the blank for forming this bag comprises a rectangular front portion -1-- and a back rectangular portion 2- both of'substantially the same dimensions -and integrally united end-to end alonga score line 3- upon the other.

The back portion .2- is provided along its'opposite longitudinal edges with similar integral binding strips '--L-- adapted to be folded along score lines -5- upon the i11- ner face of the back portion -2- and provided on one side with an adhesive for sevso as to vfold at said line one Specification of Letters Patent.

curement to the adjacent longitudinal edges outer face of the adjacent end -`l for closing the open end of the bag'.

'lhe flap- -6- is provided with a central opening -8- extending outwardly from the score line -7-, the inner end being straight and registering with said line, while the remaining portion is preferably circular for receiving a tongue presently described, on the adjacent end of the front portion -1-.

The portion of the backi-2 and flap 3- immediately surrounding the opening *8- is strengthened by an eXtra piece of paper or reinforcement -9- adhesively secured to the inner', face or flap as shown more clearly in Figs. 2 and 3.

The free end of the front portion *lis formed with a central tongue 10- eX- v'tending beyond the end edges thereof, for

entering the opening -8-, a portion of said tongue being formed by slits '11- in the main body of the front -lsaid slits being of substantially the same length, but of less length than that of the opening -8-, so as to form locking members l2- partially within the end edge ofthe portion These locking members -12- constitute the tongue l0- and are foldable along the score lines -13-- so that when folded the 'v tongue may readily enter the opening -8-.

when the flap -6- is closed and may then be unfolded upon the front face of the closed flap to hold the latter in its closed position.

TheV width of the tongue across the wings which are preferably semi-circular, is somewhat greater than thatjof the opening 8 when the wings' are unfolded, although the remaining portions of the tongue are approximately the same or slightly less width than thatof the opening.

It therefore follows that in closing, it is simply necessary -to fold the'wings 12'- forwardly toward each other along the scoreA which will allow the tongue to readily enter the opening --8, and as'soon as the flap #-6- is' brought flatwise against *12- and also the' adjacent portions of the what may be termed a finger loop, to, but preferably integral front portion -1- of the bag is reinforced by an eXtra strip -14- of similar paper adhesively secured to the inner face of the front portion flpreferably before the latter is adhesively secured to the binding strips -.4.. The tongue 4-10-- is provided, with a finger opening --15 thereby producing secured with the upper end of the front side of thebag and adapted to extend through the opening -8- in the flap -6- when the latter is foldedover upon the front face of said front side of the bag, during vwhich operation, the wings -12- are automatically compressed toward each other by'the walls of the opening to allow said walls to pass below the lower edges Yof the wings for interlocking engage# ment therewith, it being understood that the wings automatically expand for locking purposes when, the ap is folded against the front side of the balg. l

lBy attaching the nger loop directly to the upper end of the front side of the bag andpassing it through an opening in the flap which is attached to the back side of the bag causes the load to be carried by the front side through the medium of the loop, there-1 by preventing any possibility of accidental.

opening of the mouth of the bag. or loosening of the Hap when the bag is distendedv .by

the contents or load which is of the utmost importance in devices of this character, both from the point of veconomy in manufacture, rapidity of adjustment foruse and safety in conning the contents Within the bag when carried by the loo lVhat I claim is: A paper bag of the character described comprising a back portioniand a front portion united along one end and also along their opposite longitudinal edges, the upper end of the front portion being provided with a linger loop having laterally projecting wings on opposite edges thereof, the back portion being provided with a flap foldable over and upon the front faceof the front portion, said flap having an opening for permitting the finger loop to pass therethrough when the flap folded,said opening being of less width than the transverseV width of the linger loop across the wings thereof to permit the latter to interlock with the front face of the flap at opposite sides of the open- HOWARD' P.
